What Changed

If you purchased your inMOTION NGX modules before April 1st, 2026, they came preconfigured for a specific door position. You ordered a Driver Front module, a Passenger Front module and so on. Each one was programmed before it shipped.

Starting April 1st, 2026, every inMOTION NGX ships as a universal module. Instead of ordering a door-specific part number, you configure inMOTION NGX modules yourself using the MASTERCELL NGX. This is a one-time setup that takes less than a minute per module. Once configured, the module operates at its assigned door position. You can reconfigure it at any time by running this process again.

This change means you no longer need to worry about ordering the wrong module for a specific door. Every inMOTION NGX in your kit is identical until you tell it where it lives.

You need MASTERCELL NGX software revision 1.4 or higher to use this feature.  You can learn how to check your MASTERCELL NGX software version at this blog post.  

Before You Start

Before you configure inMOTION NGX modules, make sure the following are done:

  • Your inMOTION NGX modules are mounted in their doors (Step 1 in the installation manual).
  • Power and ground are connected to each module (Step 2 in the installation manual).
  • The CAN cables are spliced and connected between the inMOTION NGX modules and your IPM1 CAN network (Step 3 in the installation manual).

You will configure each module one at a time. The MASTERCELL NGX needs to see exactly one inMOTION NGX on the CAN network during this process. That means you will disconnect all but one module, configure it, then move to the next.

inMOTION NGX Door Positions

Each inMOTION NGX must be assigned to one of four positions. The position determines which CAN address the module uses and which commands it listens to on the network.

inMOTION NGX Name Location in Vehicle CAN Address
Driver Front Driver Front Door 3
Passenger Front Passenger Front Door 4
Driver Rear Driver Rear Door 5
Passenger Rear Passenger Rear Door 6

By default, all inMOTION NGX modules ship configured as Driver Front. If you are installing a 2-door vehicle, you only need a Driver Front and a Passenger Front module. For a 4-door vehicle, you will configure all four positions.

Step-by-Step: Configure inMOTION NGX

STEP 1. Make sure only one inMOTION NGX is connected to the CAN network. Disconnect the CAN wires from all other inMOTION NGX modules. The module that remains connected is the one you are about to configure.

STEP 2. Navigate to the MASTERCELL NGX main menu using the inSIGHT display. Use the UP/DOWN buttons to scroll to inMOTION and press SELECT.

Select inMOTION from the MASTERCELL NGX main menu to begin configuration.

STEP 3. The inSIGHT display shows the inMOTION CONFIG screen. The MASTERCELL NGX scans the CAN network looking for connected inMOTION NGX modules. When it detects exactly one module, the screen reads “Connect only 1 inMOTION to CAN” with “SELECT to go” on the bottom line. Press SELECT to proceed.

The MASTERCELL NGX confirms it sees exactly one inMOTION NGX on the CAN network.

If the screen displays “Waiting…” instead, the MASTERCELL NGX has not detected any inMOTION NGX modules. Verify that the module has power, is properly grounded and that the CAN wires are correctly spliced to the network.

If the screen shows that more than one inMOTION NGX was found, it will block you from proceeding. Disconnect the extra modules so only one remains on the CAN network, then try again.

STEP 4. The inSIGHT display shows a list of door positions. Use the UP/DOWN buttons to select the position you want to assign to this module: Driver Front, Passenger Front, Driver Rear or Passenger Rear. Press SELECT to confirm your choice.

Use UP/DOWN to choose the door position for this inMOTION NGX module.

STEP 5. A confirmation screen appears showing the position you selected. Press SELECT to confirm or HOME to cancel and go back to the position list. Once you confirm, the MASTERCELL NGX sends the configuration commands over CAN. This takes a few seconds while it writes the new settings and verifies the module responds at its new address.

Confirm your selection. Press SELECT to write the configuration or HOME to go back.

STEP 6. When the configuration is complete, the screen displays the new position assignment with a “Success!” message. Press HOME to return to the menu.

Configuration complete. The inMOTION NGX is now assigned to its door position.

STEP 7. Repeat this process for each inMOTION NGX module in your system. Disconnect the module you just configured from the CAN network, connect the next one and run through the steps again. Continue until every module is assigned to its door position.

Once all modules are configured, reconnect all of them to the CAN network. Navigate to System Inventory on the MASTERCELL NGX to verify that every inMOTION NGX appears at its correct position.

Troubleshooting

The screen says “Waiting…” and never finds my module.
Check that the inMOTION NGX has power on both red 14-AWG wires and is properly grounded on both black 14-AWG wires. Verify that the green and yellow CAN wires are spliced correctly to the IPM1 CAN cable. Make sure the CAN wires are not reversed — green to green (CAN LO) and yellow to yellow (CAN HI).

The screen says it found more than one module.
Only one inMOTION NGX can be on the CAN network during configuration. Disconnect the CAN wires from all other inMOTION NGX modules and try again.

I configured a module to the wrong position.
Run the process again. Connect only that module to the CAN network and assign it to the correct position. The new configuration overwrites the previous one.

We just released a new video that covers the features and benefits of our inMOTION Motor Controller Cell.

The Infinitybox inMOTION Cell

The Infinitybox inMOTION Cell

inMOTION is a unique module that connects to the CAN network of your 20-Circuit Kit.  It looks like a POWERCELL but acts differently.  Instead of turning 10 things on and off like a POWERCELL, it reverses the polarity to 5 things.  We originally designed inMOTION to control power windows and power lock actuators.  Instead of relying on a switch, inMOTION has special h-bridge relays that reverse the polarity.  This lets you change direction of things like power windows, power locks, linear actuators and valves.

That is just the beginning.  inMOTION is smarter than a POWERCELL which means that you can get express features on your windows with no limit switches.  You can also get wireless control through inLINK or a smart phone attached to inTOUCH NET.

Check out this video for a deeper dive into what inMOTION can do.

We have the solid model for the inMOTION cell available to our customers to help with their planning and mocking up process.

Nu-Crank Master Power Window Switch

/in /by

Nu-Relics has been manufacturing power windows solutions for restorations since 2005.  They pride themselves in making direct drop-in electric power windows for classic cars and trucks.  Their products use the highest quality materials and are designed with the exact bolt pattern required for your project.  They also use the exact same geometry for smooth and reliable power window action.  They also make a very clever product called Nu-Crank.  This is a switch assembly that they developed to control your power windows.  The big difference from other window switches is that Nu-Crank uses the original window crank to drive the power windows up and down.  You get the look of the original interior in your classic car with the convenience of power windows.   The Nu-Crank mounts in the location where the original crank was located.  You lift the crank to raise the power window and push down on the crank to lower it.  It is very simple and elegant.

You can very easily integrate the Nu-Crank switches into our Infinitybox system to control your power windows with our inMOTION Motor Controller Cell.  With our 20-Circuit Kit and inMOTION, you can control your power windows from any switch, that includes the Nu-Crank switches.  The MASTERCELL inputs wire to the switches and inMOTION reverses the polarity going to the motors.  It is very easy.

A customer asked us recently how if there was a way to control both the driver and passenger power windows from the driver’s side of the car without reaching over to the passenger side.  The answer is yes.  This can be done easily by adding a Double Pole, Double Throw (DPDT) switch to your harness.  A DPDT switch has two different sets of contacts inside.  It also has two switched positions.  Using this DPDT switch, you can route the driver’s Nu-Crank switch contacts to two different pairs of MASTERCELL inputs.  See the wiring diagram below.

The wire colors shown in this diagram may not match the MASTERCELL inputs or inMOTION outputs for your specific system.  Please reference the configuration sheet that came with your kit for exact wire colors.

You can easily hide this DPDT switch on the drivers side of the car.  By flipping the switch between the driver and passenger position, you get the ability to control either power window from the driver’s switch.  That way, you can control the passenger window without having to reach across the car to move the Nu-Crank switch.

Since the MASTERCELL inputs require so little current to trigger the input, you can use practically any DPDT switch.  The MASTERCELL inputs require less than 1 milliamp so you do not have to worry about damaging the contacts of your DPDT switch of the contacts in the Nu-Crank switch after repeated operation.
